Eazeye Radiant 15.6-inch portable transflective LCD review

Eazeye sent me a sample of the Radiant 15.6-inch transflective LCD review for review after I wrote about the Eazeye 2.0 24-inch reflective LCD monitor last August. Yes, there’s been a little bit of miscommunication as I got a transflective LCD (TLCD) launched last year, instead of the new reflective LCD (RLCD). But that’s OK. While those are two different technologies, both monitors are designed to rely on natural light, and I assumed either would perform better outdoors and reduce eye strain compared to traditional portable monitors or laptop displays. Let’s find out. Eazeye Radiant unboxing and specifications I received the portable monitor in a retail box. The main surprise here was that I was expecting a 24-inch monitor, and this looked a little small. I quickly realized the Radiant was a 15.6-inch model instead. We can get part of the specifications on the back side of the package. But […]

reTerminal E1001/E1002 – ESP32-S3-powered monochrome/color ePaper displays for dashboards, digital signage

Seeed Studio’s reTerminal E1001 and E1002 are two ePaper displays featuring an ESP32-S3 WiFi and Bluetooth LE wireless microcontroller suitable for dashboards or digital signage applications. The only difference between the two reTerminal E-series displays is that the E1001 features a 7.5-inch monochrome display, while the E1002 integrates a 7.3-inch 6-color ePaper display. Both come with a 2,000 mAh battery offering up to 3 months of battery life, a 32MB SPI flash, a microSD card slot, a microphone and a buzzer, temperature and humidity sensors, an 8-pin GPIO header, and a few buttons and LEDs. reTerminal E1001/E1002 specifications: Wireless SoC – Espressif Systems ESP32-S3 dual-core microcontroller with 8MB PSRAM Storage 32MB SPI flash MicroSD card slot up to 32GB (FAT32 file system only) Display E1001 – 7.5-inch Monochrome ePaper display with 800×480 resolution E1002 – 7.3-inch “Full Color” (i.e., 6-color) ePaper display with 800×480 resolution Audio Microphone (3) for voice […]

ThinkNode M1/M2 Review – Getting started with Meshtastic

I’ve been writing about Meshtastic firmware and hardware since 2020, but I never had the opportunity to test it myself. This has now changed as Elecrow sent us the ThinkNode M1 and ThinkNode M2 Meshtastic nodes for review. Both rely on Semtech SX162x radios, but the M1 is based on a Nordic Semi nRF52840 Bluetooth MCU with a 1.54-inch E-Ink display and GPS, and the smaller M2 is based on an ESP32-S3 chip and a 1.3-inch OLED but lacks a built-in GPS module. Since I’ve never used Meshtastic before, this “review” will be more like a Getting Started Guide from a beginner’s perspective. After an unboxing and a teardown, I’ll test messaging, GPS sharing, and the range I can get in a suburban environment in Thailand. ThinkNode M1/M2 unboxing Both packages look similar, with a plastic case and a white cover. The ThinkNode M1’s main features include a high-gain antenna, […]

ThinkNode M2 ESP32-S3-based Meshtastic handset features 1.3-inch OLED display, 1,000 mAh battery

Elecrow ThinkNode M2 is yet another Meshtastic handset for off-grid messaging and GPS coordinate sharing based on an ESP32-S3 module providing Bluetooth connectivity to a smartphone, and a Semtech SX1262 LoRa transceiver for low-power long-range wireless connectivity. It’s an evolution of the ThinkNode-M1, itself similar to the LILYGO T-Echo, based on a Nordic Semi nRF52840 Bluetooth module and SX1262 LoRa transceiver with an external antenna housed in a 3D printed enclosure. The new ThinkNode M2 is very similar but features a more powerful ESP32-S3 module instead, relies on a 1.3-inch OLED display instead of a 1.54-inch e-paper display, and is housed in an ABS plastic case. ThinkNode M2 specifications: Core module – ESP32-S3 module (looks to be ESP32-S3-WROOM-1 on the photo below) SoC – ESP32-S3 CPU – dual-core 32-bit microcontroller @ 240MHz Memory – 512KB SRAM, 8MB PSRAM Storage – 384KB ROM 4MB flash Wireless – 2.4GHz Wi-Fi and Bluetooth […]

DASUNG Paperlike 13K ports epaper color monitor

New color e-paper monitors – 13.3-inch DASUNG Paperlike 13K and 23.5-inch BOOX Mira Pro Color

Back in 2023, DASUNG launched its first color E-Ink monitor, quickly followed by BIGME B251 computer and standalone E-Ink monitor. Both were based on the same 23.5-inch E-ink Kaleido 3 color display with 3200×1800 resolution, and were rather pricey at $1,529 (Indiegogo price) and $1,299 (Kickstarter price), respectively. Let’s revisit color e-paper monitors in 2025 with two new models that were just announced: the DASUNG Paperlike 13K 13.3-inch e-ink color monitor and BOOX Mira Pro (Color version) with the same 23.5-inch E-Ink Kaleido as competing monitors launched in 2023. Those monitors are particularly well-suited for people spending long hours in front of the screen, and don’t need to watch video and play games due to the lower refresh and ghosting effect. It’s supposed to be friendlier to eyes, and there’s no blue light.

FOSSASIA 2025 – Operating systems, open hardware, and firmware sessions

The FOSSASIA Summit is the closest we have to FOSDEM in Asia. It’s a free and open-source event taking place each year in Asia, and FOSSASIA 2025 will take place in Bangkok, Thailand on March 13-15 this year. It won’t have quite as many speakers and sessions as in FOSDEM 2025 (968 speakers, 930 events), but the 3-day event will still have over 170 speakers and more than 200 sessions. Most of the sessions are for high-level software with topics like AI and data science, databases, cloud, and web3, but I also noticed a few sessions related to “Hardware and firmware” and “Operating System” which are closer to what we cover here at CNX Software. So I’ll make a virtual schedule based on those two tracks to check out any potentially interesting talks. None of those sessions take place on March 13, so we’ll only have a schedule for March […]
